Lamp assembly for a vehicle

Abstract

A lamp assembly for illuminating a ground area adjacent a vehicle is disclosed. The assembly includes a housing; an outer lens covering the housing; a plurality of light emitting diode (LED) light sources arranged in the housing; and a reflector mounted in the housing. The light emitted from the plurality of LED light sources is captured by the reflector which reflects light towards the lens, the lens directing light generally downward towards the ground area. The light output from the lamp assembly appears to be emitted from a single light source.

AI Technical Summary

Benefits of technology

[0021]According to a second aspect, there is provided lamp assembly for reducing glare, including: a plurality of light emitting diode (LED) light sources; a reflector positioned above the plurality of LED light sources so that light is emitted from the plurality of LED light sources upwards into the reflector, the reflector including a plurality of reflective segments, each of the plurality of reflective segments illuminated by each of the plurality of LED light sources; wherein, the reflector substantially removes the directionality of the light emitted from the plurality of LED light sources to reduce glare.

Problems solved by technology

As the power of the LED increases, the brightness can increase to a level whereby an uncomfortable glare is experienced by a person viewing the LED directly.

In the past, lamp assemblies that have been used to provide ground illumination have achieved the required level of brightness but in the process created too much unwanted glare.

To reduce the glare, a lower power light source would have to be used which compromises the ability of the lamp assembly to appropriately illuminate the ground area.
